oAsme non ORGAN-BLOWERS.

. citizen of the United States, and a resident of Hartford, in thecounty of Hartford and State of Connecticut, have invented a new andImproved Casing for Organ-Blowers, of which the following is aspecification.

My invention relates tothe class of devices above named, and ancbject'of the iii-- vention, among others, is to provide a casing ofthis character that shall be extremely strong and rigidwhile being ofminimum weight.

One form of device embodying the invention, and in the construction anduse of which the object above set out as well as others may beattainedis illustrated in the accompanying drawings, in which- Figure 1a view in front elevation of a' casing embodying my invention with amotor located therein. Fig. 2 is a view in side elevation of my improvedmotor casing.

The casing herein illustratedand described incloses mechanism operatedby a motor located in one end of the casing and separated from that partin which the mechanism is contained, andsaid casing also embodies meanswhereby the motor is readily accessible, the numeral fidenoting the bodyof the casing, in thepresent instance a fan casing,- having an inlet 6and an outlet or exhaust 7, the chamber in the body being inclosed atthe end opposite the inlet by a Wall 8. A motor 9 is located in aprojecting part 10 from the body, beingsupported upon a motor base l1,and the case as a whole being supportedupon standards The shaft of themotor is connected with thefan shaft within the casing, the motorserving for driving said fan.

It is essential that the motor shall be readily accessible, but beingextremely heavy, as is usual'in'devices of thisclas's. in

providing means for gaining access to the motor its rigid support mustbe carefully borne in mind, as it is of the utmost importance that thepart sustaining the motor shall be rigid and immovable with respect tothe part sustaining the fan shaftto which the motor is secured. Inattaining this end I cut away the upper portionof the casing as at 13,cutting away the extreme upper part 14: entirely as well as the extremelower part 15 at the uppersurface of the motor base. In so cutting awaythe casing to gain access to the motor I remove the metal of thecylindrical casing on acurved line 16 which forms a brace 1'7 betweenthe projectmg part or support 10 for the motor and the upper portion ofthe body part '5, this brace by this formation being integral with thebody and motor support and producing a very rigid structure.

I claim'- v 1 l. A casing including a cylindrical"bodypartthe lowerportion of which is extended to constitute a motor support formed on anarc of a circle equal to thatof the body part, and an integral bracingwall extending between said motor supporting part and body. s v v 2. Acase including a 1 body portion of cylindrical form' and ai -extensionon the tension being formed onthe same are as that of the body part, andlntegral bracing walls the edges of which are formed on" arcs of thebody part to the upper part of said in said motor support.
